“Ironside,” starring Blair Underwood in an updated version of the Raymond Burr police drama, will air its final episode on Wednesday. Burr’s “Ironside” aired from 1967-75, but low ratings will keep the new series to a total of four episodes.

“Welcome to the Family,” a Thursday night comedy about a young couple’s unplanned pregnancy, won’t have a chance to say goodbye. Its last airing was this week.

Replacing “Ironside” on Wednesday nights in November and December will be a mix of shows including episodes of “Dateline” and “Saturday Night Live” holiday-themed specials, NBC said.

“Parks and Recreation” episodes and specials will fill in for the departed “Welcome to the Family,” the network said Friday.
